Directed, undirected! Rhodium(III)‐catalyzed double CH bond activation (one directed, one undirected) provides an efficient route to biaryls (see scheme; DG=directing group). Significant kinetic isotope effects for both reaction partners and H/D scrambling between them are interesting experimental findings. While the mechanism is still unclear, a rhodium(V) species is invoked in the catalytic cycle
有向,无向!铑(III)催化的双CH键活化(一个是定向的,一个是非定向的)提供了通往联芳基的有效途径(请参见方案; DG =导向基团)。有趣的实验发现是,反应伙伴的动态同位素效应以及它们之间的H / D争夺都非常重要。虽然机理尚不清楚,但在催化循环中会调用铑(V)物质。
